Galois structure on integral valued polynomials
Bahar Heidaryan, Matteo Longo, Giulio Peruginelli
We characterize finite Galois extensions of the field of rational numbers in terms of the rings , recently introduced by Loper and Werner,…
Design of Fuzzy self-tuning PID controller for pitch control system of aircraft autopilot
Nima Beygi, Maani Beigy, Mehdi Siahi
A variety of control systems have been proposed for aircraft autopilot systems. Traditional approaches such as proportional controller and conventional PID (CPID) controller are wi…
A new version of fermion coupled coherent states method: Theory and applications in simulation of two-electron systems
Mohammadreza Eidi, Mohsen Vafaee, Ali Reza Niknam +1
We report a new version of fermion coupled coherent states method (FCCS-II) to simulate two-electron systems based on a self-symmetrized six-dimensional (6D) coherent states grid.…
Complicated high-order harmonic generation due to the falling edge of a trapezoidal laser pulse
H. Ahmadi, M. Vafaee, A. Maghari
High-order harmonic generation (HHG) is investigated for H and its isotopomers under seven- and ten-cycle trapezoidal laser pulses at 800 nm wavelength and =4$\times 10^{1…
The category of ordered Bratteli diagrams
Massoud Amini, George A. Elliott, Nasser Golestani
A category structure for ordered Bratteli diagrams is proposed in which isomorphism coincides with the notion of equivalence of Herman, Putnam, and Skau. It is shown that the natur…
The stability and gravitational Newtonian limit of a modified Randall-Sundrum model
Shahrokh Parvizi, Mojtaba Shahbazi
For a modified Randall-Sundrum model [Phys. Rev. D 88 (2013) 025048], the graviton equations are derived and the mass spectrum found. The latter includes a massless graviton and a…
